`JOHN BACHUS, OF JERSEY CITY, NEW JERSEY.

ADJUSTABLE DooR-FRAM E.

SPECIFICATION- forming part of Letters Patent No. 680,015, dated August 6, 1.901. Application led March 28,1901. Serial No; 53,214. (Nomodel.)

To all whom t may concern,.-

Beit known that I, JOHN BACHUS, a citizen of the United States, anda resident of Jersey City,in the county of Hudson and State of New Jersey, have invented anew and Improved Adjustable Door-Frame, of which the following is a full, clear, and exact description.

The invention relates to carpentry; audits object is to provide a new and improved adjustable door-frame arranged to permit convenient and ready adjustment of the rabbetstrip at any time to insure proper opening and closing of the door without requiring planing or rehanging of the door, as has been so frequently practiced heretofore, to overcome the defects caused by swelling, shrinking, settling, or warping of the door-frame or the door, or both.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims. Y

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a sectional plan view of the improvement. Fig. 2 is a like view of the same previous to the adjustment of the rabbetstrip, the section of the trimming-board being removed to give access to the adj ustingV device for the rabbet-strip. Fig. 3 is a front elevation of the improvement. Fig. 4 is a side elevation of the same. Fig. 5 is a sectional plan view of a modified form of the improvement, and Fig. 6 is a perspective view of the side of the head-jamb in a separated position.

On the studA of the door-frame are secured the usual laths and plaster B, and the doorjamb C, forming, with the removable section D' of the door-trimming D, a guideway E, in

which is adjustably held a rabbet-strip F, having a door-stop F,either integrally formed therewith or separately secured thereto. By adjusting the rabbet-strip F in the guideway E toward or from the door G it is evident that a proper fit can be obtained at any time between the said rabbet-strip and the door G to insure proper opening and closing of the door at all times. The rabbet-strip F is held in position on the stud A by screws H, two, three, or more in number, preferably formed with countersunk heads, according to the character of the door-frame and its door.

In order to adjust the rabbet-swtrip F for the purpose,lagscrews I are employed screwing in the stud A,the heads I' of which screws abut either directly on the inner face of the rabbet-strip F or against a metallic wearplate J, secured to the inner face of the said rabbet-strip. Usually two such lag-screws I are employed and'arrangeddiagonally on opposite sides of the corresponding fasteningscrew H, as is plainly indicated in Fig. 4, it being understood that when the section D of the door-trimming B is removed by the carpenter then access is had to the inner portionof the guideway E and to the lag-screws I, so that the same can be readily turned by the application of a suitable wrench on the heads I ofthe screws to screw the same inward or outward inthe stud A, and thereby adjust the rabbet F correspondingly from or toward the do'or. Previous to making the desired adjustment the screws H are loosened, and after the desired adjustment has been made then the screws H areagain ,screwed up so as to bring the inner face of the wearplate J in firm contact with theheads of the lag-screws I to securely hold the rabbet-strip Fin position and in proper position relatively to the door G. (See for comparison Figs. 1 and 2.)

As shown in Fig. 5, the jamb C forms with the-rabbet-strip F2 a door-stop for the door to abut against when closed, said rabbetstrip being adj ustably held in the guideway formed between the jamb C' and the removable section D2 of the door-trimming D3, and lag-screws l2 arevemployed by adjusting the said rabbet-strip the same as above described in reference to Figs. 1 and 2. Screws H and H2 serve to securely hold the rabbet-strip in place on the stud A and the jarnb C after adjustment is made.

In order to permit convenient moving of .the rabbet-strip without forming an open,

It will be seen that in my invention the jamb O is cut away on one side and forms inV connection with the detachable section D of the trimming a guideway for the rabbetstrip and also a housing for the lag-screws, to which access may be had by removing the detachable trimming-section D without marring the plaster-line. These lag-screws form the back 'bearing for the rabbet-strip to sol-y idly rest against, and with the screws H permit the rabbet-strip to be rectilinearly and.

integrally adjusted.

A distinct and valuable feature of my invention is to be found in the fact that in the slamming of the door on the rabbet-strip F the impact is not borne by the adjustingscrews, but comes against the stationary doorjamb C, Which is firmly nailed in the usual way to the sjtudding. This preserves the operative condition of the adjusting (ie'vices,

yjamb to resist the impact of the slamming of the door, as set forth.

2. A door-frame havingv a stud, a jamb selcured thereto, but cut away on one side, a

trimming-board forming with said jamb a guideway, a rabbet-'strip mounted in said guideway, and means between said rabbetstrip and said stud, to integrally and rectilinearly adjust the rabbetstri p relatively to.

the door, said rabbet-strip having throughout its adjustmenta solid and direct abutment against the rigid portion of the door-jamb to resist the impact of the slamming of the door, as set forth.

3. A door-frame havinga stud, a fixed jamb cut away on one side, a trimming-board forming with the jamb a guideway, a rabbet-strip ad jnstably held in said g'uideway, means for integrallyand rectilinearly adjusting the rabbet-striptoward or from the door, said means consisting of lag-screws seated ,in the stud and forming a back bearing for the rabbetstrip, and fastening-screws for holding the rabbet-strip in position on said stud, said rabbet-strip having throughout its adjustment a solid and direct abutment against the rigid portion of the door-jamb to resist the impact of the slamming of the door, as set forth.

4. A door-frame having a stud, a fixed j amb cut away on one side, a trimmingboard form ing with the jamb a guideway, the trimming; board being made in sections, one of which is removable to give access to said guideway, a rabbet-strip adj ustably held in said guide- Way, and means for adjusting the rabbet-strip toward or from the door, said means comprising lag-screws screwing in the stud and abutting with their heads against the inner face of the rabbet-strip to form a back bearing for the same and fastening screws extending through the rabbet-strip into the stud, said 'rabbet-strip 'having throughout its adjustment a solid and direct abutment against the rigid portion of the door=jamb to resist the impact of the slamming of the door,- as set forth.

5. A door-frame having a stud, a fixed jamb cut away on one side, a trimming-board forming with the jamb a guideway, the trimmingboard being made in sections, one of which is removable to give access to said guideway, a rabbet-strip adj ustably held in said guideway, and means for integrally and rectilinearly adjusting the rabbet-strip toward or from the door, said means comprising lagscrews screwing in the stud, wear-plates on the rabbetstrip and against which abut the heads of said lag-screws and fastening-screws passing through the rabbet-strip into the stud, said rabbet-s'trip having throughout its adjustment a solid and direct abutment against the rigid portion of the door-jamb to resist the impact of the slamming of the door, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN BACH US.
